Combined Basal-bolus Insulin and Post-exercise Carbohydrate Feeding Strategy in T1DM

Not Applicable
Completed
Conditions
Type 1 Diabetes Mellitus
Interventions
Drug: Basal insulin dose
Registration Number
NCT02204839
Lead Sponsor
Northumbria University
Brief Summary

The investigators hypothesise that reducing basal insulin dose (Glargine, Lantus, Sanofi-Aventis, or Detemir, Levemir, Novo Nordisk), whilst employing current carbohydrate feeding and rapid-acting insulin dose recommendations will protect patients with type 1 diabetes from early- and late-onset hypoglycaemia following evening time exercise.
